#2227 hours of machine time, $70 of plastic filament, multiple failed parts and hours of hand finishing. Truly, this is the future of manufacturing.

While I know you have the hype around 3D-printing in mind, there is no sign that this guy consider this anything else than a hobby.
But of cause, this article does in many ways highlight the problems with current 3D-printing technology, and why it currently is mostly a rather limited prototyping tool. This would be the case even for more professional 3D-printers. Now most of the hype is gone, and I think most people realize that 3D-printers will remain a prototyping tools for the forseable future.

To make just 1 unit of a decently complex unique design for only $70 in materials, 227 hours of machine time, and a reasonable amount of human assembly time, is seriously impressive!
3D printing isn't the future of mass manufacturing, but it is getting much much closer to being the future of prototyping and one-offs for pretty much every plastic thing (and some metal ones, too), especially as the hobby level printers keep getting better.
If you're not impressed with this, you likely haven't ever gotten quotes from a quick turn plastics manufacturing shop.

While I agree with the sentiment, on the flipside, this is a completely custom prototype for only a little over a week of machine time and a few hours of hand finishing. It would be absurd to try and manufacture that case at volume using 3d printing that slow but this is stuff that could be easily injection molded once the design is finished. Trying to come up with that same product as a one off prototype without 3D printing would make the costs for this case seem downright cheap.
Just look at all of the custom parts that went into this.

3D printed drive rails and hinges is honestly a pretty bad idea even for a prototype, and it basically doubled the time it took him to assemble it. I'd say it's a pretty big leap forward that some average Joe can print out a custom case like this and have it come out looking fairly professional.

While I agree that people were thinking to achieve more when buying a 3d printer and then many realised it's not always easy and straightforward to print thinks in mind, I still wouldn't call this a hype.
It's an advancement and we are the early adapters.
Even in the current state, I managed to print many useful things, only by downloading 3d models by the fraction of the price I would be paying if I were to buy those things from shops.
I also realised that 3d printers are not the same as few years ago, they are more precise, accurate and handling the errors better than previous models.
So I am a bit more hopeful than you for the foreseeable future. :)

Who on earth would want to make a computer case from plastic? Cutting, folding, drilling and riveting sheet metal is fast and economical, even with basic hand tools. You can buy a dizzying array of fixtures and fittings from McMaster-Carr or your local equivalent.
I'm not fundamentally opposed to 3D printing, but I do have a bone to pick with the "maker community", which seems to have a pathological aversion to basic shop class skills. If you want to make a custom PC case, then by all means do so, just don't stink out your house with ABS fumes in the process - buy a copy of Basic Benchwork by Les Oldridge and Sheet Metal Work by R.E. Wakeford, scrounge up some tools and have at it.

#8I'm trying to figure out how one manages 24 and 48 hour prints without potentially setting the house on fire.
As far as I am aware, no FDM 3D printer is safe to run unattended, overnight without supervision. I know there are ways to make things safer, with various interlocks, fire suppression items (like those kitchen vent-hood pucks), cameras for monitoring, etc. But I still wouldn't trust just letting something like that run.
I've yet to do anything with 3D printing, so maybe I am just out of the loop on this. I do know that software and hardware has come far enough to allow for print stop/re-starting (such as when reloading filament in the middle of a large job). Maybe that's how these long prints are done without the danger?

FDM printers, from what I recall, existed as commercial products for prototyping long before reprap and other early hobbyist efforts came to fruition:
https://en.wikipedia.org/wiki/3D_printing#History
...and according to that link, even more advanced processes (stereolithography, for instance) were being explored in the 1980s and 90s.
These systems have long been available on the commercial market - albeit for (likely) a steep price. What has really happened is that the price on the systems have dropped steeply, and they are now available to the hobbyists with the skills to use them.
Before, that was a near impossibility unless you worked for a company that had a commercial system - and would let you near it.

I'm definitely in agreement with you here; it bothers me a bit to see an instructable or similar where one of the essential requirements always seems to be a 3D printer. It's always a breath of fresh air when that isn't true.
In many, many cases, most things done by "makers" can be done without 3D printing anything, and be more accessible to others. I can understand needing or using one when you need something custom to fit or retrofit into an existing commercial product. Even there, with a bit of thinking, one can generally come up with a solution where a 3D printer isn't needed.
I'm starting to see this same kind of attitude creep into laser cutters - projects that seem to think everyone has access to one, when that isn't necessarily true. For instance, I know where I could go to get access to one (and 3D printers, etc) - but it would be about a 50 mile drive for me. Far enough where I would seriously consider other alternatives.
I do have to say, though, that the 3D printer (and other CNC tools commonly used by the maker community) has allowed for a lot of people who may not have the dexterity or other related abilities the chance to design and build some fantastic creations. Furthermore, there are more than a few things that just couldn't be done any other way (or at least as cheaply or quickly). There is also the nice idea that (at least in theory) one can take those same files and use them with other CNC processes. In the case of laser cutters, if you can print the files full-sized, you can even cut them out manually with a coping saw or other more "manual" tooling.
